Serialize branched class (with lists)

Question

this is my xml script which i would like to Serialize:

And this is my serialize class :

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Xml.Serialization;
using System.IO;


namespace XML_Example
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void btnSerialize_Click(object sender, EventArgs e)
        {
            Reports reports = new Reports();
            reports.listOfReportTypes = new ListReportTypes();
            reports.listOfReportTypes.reportsType.Add(new ReportType());
            reports.listOfReportTypes.reportsType.Add(new ReportType());
            reports.listOfReportTypes.reportsType[0].name="ABCD.Record.ABC, abcd, Version=1.0.3.4, Culture=neutral, PublicKeyToken=null";
            reports.listOfReportTypes.reportsType[0].listOfReportColumns = new ListOfReportColumns();
            reports.listOfReportTypes.reportsType[0].listOfReportColumns.columnProperty.Add(new ColumnProperty());
            reports.listOfReportTypes.reportsType[0].listOfReportColumns.columnProperty.Add(new ColumnProperty());
            reports.listOfReportTypes.reportsType[0].listOfReportColumns.columnProperty.Add(new ColumnProperty());
            Serialize(reports);
            Close();

        }
        static public void Serialize(Reports reports)
        {
            XmlSerializer serializer = new XmlSerializer(typeof(Reports));
            using (TextWriter writer = new StreamWriter(@"C:\Users\eladh\Desktop\יצירת XML\Elad.xml"))
            {
                serializer.Serialize(writer, reports);
            }
        }
    }
    [XmlRoot ("Reports")]
    public class Reports
    {
        [XmlElement ("ListReportTypes")]
        public ListReportTypes listOfReportTypes { get; set; }
        public Reports() { }

    }
    public class ListReportTypes
    {
        [XmlElement("ReportType")]
        public List reportsType { get; set; }
        public ListReportTypes() 
        {
            reportsType = new List();
        }

    }
    public class ReportType
    {
        [XmlAttribute ("Name")]
        public string name { get; set; }
        [XmlElement ("ListOfReportColumns")]
        public ListOfReportColumns listOfReportColumns { get; set; }
        public ReportType()
        {
            name = string.Empty;
        }
    }
    public class ListOfReportColumns
    {
        [XmlElement("ColumnProperty")]
        public List columnProperty { get; set; }
        public ListOfReportColumns()
        {
            columnProperty = new List();
        }
    }
    public class ColumnProperty
    {
        [XmlArrayAttribute("DBColumn")]
        public string DBColumn { get; set; }
        [XmlArrayAttribute("Display")]
        public string Display { get; set; }
        [XmlArrayAttribute("IsColumnDisplay")]
        public bool IsColumnDisplay { get; set; }
        [XmlArrayAttribute("IsSelectedByUser")]
        public bool IsSelectedByUser { get; set; }
        [XmlArrayAttribute("SelectedPosition")]
        public int SelectedPosition { get; set; }
        public ColumnProperty()
        {
            DBColumn = string.Empty;
            Display = string.Empty;
        }
    }
}

When I run it, it returns an error: System.InvalidOperationException

What is wrong? Is there a problem with the class or with the serialization?
